Now that we've defined it, we can eat it up. I didn't realize until Marc Jacobs' Spring collection that I've always been lovin' Lurex. A sucker for anything sparkly, Lurex adds a smidgen of Studio 54 to any item. Many of us won't be able to afford MJ come Spring, so scour your local vintage shop for Lurex infested items. Either way, hop on this trend before it's hot.
